Rotating assembly balance
I hate to bring this up now but I only recently read about it when researching potential V8 engines for my Sport. The Explorer 5.0L rotating assembly is apparently set up for 50 ounce-inches of external balance provided by the front balancer. According to my JEGS catalog the 302HO engine is also set up for 50 oz-in of external balance. Also, according to JEGS, most of the Mustang 302s and the 351W are set up for 28 oz-in of external balance. This becomes a significant issue when attempting to stroke the Explorer 5.0L because all of the stroker kits are for Mustang engines. The differences may only be significant for racing engines running very high speeds but I think it is something to investigate. Modifications to the Explorer balancer may be required. How much physical difference is there between the Explorer and Mustang balancers?
Thanks for the quick reply. . .
Yes, I see the flywheels are different and am using the EX.
